To spray gas at an appropriate timing.SOLUTION: A pump-type gas spray device that sprays gas to a detection surface of a sensor of a vehicle in a cycle of intake and spray includes a control unit that acquires sensor adhesion information including the adhesion frequency of adhering matter on the detection surface and an amount of adhesion, determines gas spray intervals on the basis of the sensor adhesion information, intermittently sprays the gas in the cycle when the adhesion frequency or the amount of adhesion is less than a predetermined threshold, and continuously sprays the gas in the cycle when the adhesion frequency or the amount of adhesion is equal to or more than the threshold.SELECTED DRAWING: Figure 8
【課題】適切なタイミングで気体を噴射する。【解決手段】車両のセンサの検知面に吸気及び噴射のサイクルで気体を噴射するポンプ式の気体噴射装置であって、検知面に対する付着物の付着頻度または付着量を含むセンサ付着情報を取得し、センサ付着情報に基づいて気体の噴射間隔を決定し、付着頻度または付着量が予め定めた閾値未満である場合に、前記サイクルで断続的に気体を噴射させ、付着頻度または付着量が前記閾値以上である場合に、前記サイクルで連続的に気体を噴射させる制御部を備える。【選択図】図8
